Fabgl PS2Controller.begin and Rebooting #51

Closed elbow closed 4 years ago

elbow commented 4 years ago

I have a devkit v1 with bitluni's 14 bit VGA wiring.

FabGL VGA out works fine if I map to the most significant bits for each colour.

But PS2Controller just causes my ESP32 to crash and reboot over and over.

14 bit vga uses up a lot of pins, so there's not much left.

I wired the audio output on D25 which is normal for fabgl.

And I hooked up D5 and D26 using the series resistor and the pull-ups per your schematic for the PS2 keyboard.

I modified one of the example scripts and initialised with

PS2Controller.begin(GPIO_NUM_26, GPIO_NUM_5, GPIO_NUM_39, GPIO_NUM_39);

The result is this, over and over:

18:08:17.701 -> assertion "0 && "invalid register base"" failed: file "/Users/steve/Library/Arduino15/packages/esp32/hardware/esp32/1.0.4/tools/sdk/include/ulp/esp32/ulp.h", line 299, function: uint32_t SOC_REG_TO_ULP_PERIPH_SEL(uint32_t)

18:08:17.735 -> 
18:08:17.735 -> Rebooting...

Can anyone assist me in getting on track?

As I mentioned, the vga-only examples do work.

Hello, sorry for the delay. Because PS/2 ports are handled by the ULP processor, only few pins are actually usable. They are: GPIO_NUM_2 GPIO_NUM_4 GPIO_NUM_12 (with some limitations) GPIO_NUM_13 GPIO_NUM_14 GPIO_NUM_15 GPIO_NUM_25 GPIO_NUM_26 GPIO_NUM_27 GPIO_NUM_32 GPIO_NUM_33

Hi,

Thanks for coming back. I built your design too and it works great. So now I have bitluni's with the 14 bit VGA and yours with less colours but with the PS2 interfaces.

Thanks.
